<1. Embodiment of the present disclosure>

[1-1. Outline]

FIG. 1 is a diagram illustrating an outline of one embodiment of the present disclosure. As shown in FIG. 1 , an information processing apparatus 10 according to this embodiment includes a display 15 and a touch panel 16 integrated with the display 15 .

The information processing apparatus 10 displays lists each having list items 21 on the display 15 . For example, the information processing apparatus 10 displays a target list 23 each having list items 21 and a plurality of sub-lists 25, as shown in FIG. 1 . The sub-list 25 displays more detailed information than the target list 23 . In this embodiment, the target list 23 is displayed as a list to be operated by the user. However, the sublist 25 can also be manipulated by the user.

The information processing apparatus 10 changes the method of displaying the list when the user has performed a certain operation or when the internal state of the application has changed. More specifically, the information processing apparatus 10 performs display control such that lists are combined/separated in response to user operations detected by the touch panel 16 . When combining lists, the information processing apparatus 10 combines the sub-list 25 to the target list 23 by, for example, gradually moving the sub-list 25 closer to the target list 23 . Meanwhile, when separating the list, the information processing device 10 creates a new sub-list 25 by, for example, gradually arranging the list items 21 separately from the target list 23 .

When combining/separating the lists displayed on the display 15, the information processing device 10 performs control to gradually change each list item on the display screen. Therefore, the user can check in advance the list items to be combined to the target list 23 or the list items 21 to be separated from the target list 23 before the combining/separating of lists is completed. In addition, the user is also able to cancel the display control of the coupling/separation before the coupling/separation is completed while viewing the list item 21 to be coupled/separated.

The sublist 25 is an auxiliary list of the target list 23 . Thus, as described above, the sub-list 25 has arranged therein the list items 21 presenting more detailed information than the target list 23 . Thus, the information presented by the target list 23 becomes more detailed when the lists are combined. Changes in displayed information of each list by coupling/separation of lists are described in detail in [2-5. Change of displayed information] below.

The outline of the information processing device 10 according to one embodiment of the present disclosure has been described above. Next, the configuration of the information processing apparatus 10 according to this embodiment will be described with reference to FIG. 2 .

[1-2. Basic configuration]

FIG. 2 is a configuration block diagram showing the configuration of the information processing apparatus 10 according to this embodiment. As shown in FIG. 2 , information processing device 10 includes control unit 11 , RAM (Random Access Memory) 12 , storage medium 13 , display processing unit 14 , display 15 , touch panel 16 , operation unit 17 and communication unit 18 .

The control unit 11 functions as an arithmetic processing unit and a control unit, and controls each component of the information processing device 10 . More specifically, as shown in FIG. 2 , the control unit 11 according to this embodiment includes a CPU (Central Processing Unit) 111 and a GPU (Graphics Processing Unit) 112 .

The CPU 111 controls each component of the information processing device 10 according to various programs. In addition, the CPU 111 may also be a microprocessor.

The GPU 112 is a display control unit that generates an image to be displayed on the display 15 or changes a display screen in response to a user operation. More specifically, the GPU 112 performs display control so that a plurality of lists each having list items 21 arranged therein are displayed on the display 15. In addition, the GPU 112 performs display control in response to a user operation so that the list items 21 of the second list, which are sublists of the first list, are combined with the first list.

Alternatively, the GPU 112 may perform display control such that a single list in which the list items 21 are arranged is displayed on the display 15. In this case, the GPU 112 may perform display control such that new list items gradually appear in the list in response to user operations.

Meanwhile, the GPU 112 can also perform display control such that the list items 21 are gradually separated from the first list in response to a user operation, and a new list is created by arranging the separated list items 21.

The GPU 112 performs display control of such joining/separating lists in response to user operations detected by the touch panel 16. For example, when a pinch-in/out operation is detected, the GPU 112 performs display control such that lists are combined/separated according to a change in distance between two fingers touching the touch panel 16. Alternatively, the GPU 112 may perform display control such that the lists are combined/separated according to the movement amount or movement speed of the finger touching the touch panel 16. Note that display control of the GPU 112 performed in response to user operations will be described in detail in <2. Coupling/Separation of Multiple Lists> to <4. Operation Processing>.

A RAM (Random Access Memory) 12 temporarily stores programs used in the operation of the control unit 11 , parameters appropriately changed during operation, and the like.

The storage medium 13 stores programs and operating parameters and the like used by the control unit 11 . The storage medium 13 also stores content such as moving image data and music files.

Note that the storage medium 13 can be, for example: non-volatile memory, such as flash ROM (or flash memory), EEPROM (Electrically Erasable Programmable Read-Only Memory) or EPROM (Erasable Programmable ROM); , such as hard disks or disc magnets; optical discs, such as CD (Compact Disc), DVD-R (Digital Versatile Disc Recordable) or BD (Blu-Ray Disc (Blu-Ray Disc, registered trademark)); or, such as MO ( Magneto-optical) disk storage media.

The display processing unit 14 causes the display 15 to output the image data output from the GPU 112 according to the display control of the GPU 112.

The display 15 is a display device that outputs a display screen input from the display processing unit 14 . This display 15 may for example be a display device such as a Liquid Crystal Display (LCD) or an organic EL (Electro Luminescence) display. In addition, the display 15 according to this embodiment displays, for example, a list including list items 21 .

The touch panel 16 is a detection unit that detects user operations on the screen. For example, the touch panel 16 detects the position (operation position) of an input object such as a finger touching the screen, and detects a user operation from a change in the operation position over time. Examples of user operations detected by the touch panel 16 include pinch-in, pinch-in, drag, flick, tap, and double-tap. A touch panel 16 is provided integrally with the display 15 . In addition, the touch panel 16 outputs the detected user operation to the control unit 11 . Although the touch panel 16 is given as an example of the detection unit in this embodiment, the information processing device 10 according to the present disclosure is not limited thereto. For example, the information processing apparatus 10 may use a detection unit that detects a user's operation in a non-contact state, such as a proximity sensor.

The operation unit 17 receives a user's operation instruction, and outputs information on the operation to the control unit 11 . The operating unit 17 may be a physical structure such as a button or a switch.

The communication unit 18 is a module that communicates with a communication terminal. Specifically, the communication unit 18 includes: a receiving unit that receives data from the communication terminal; and a sending unit that sends data to the communication terminal. In addition, the communication unit 18 can transmit and receive data via short-range wireless communication such as Wi-Fi or Bluetooth.

The configuration of the information processing device 10 according to this embodiment has been described in detail above. Next, display control performed by the GPU 112 of the information processing device 10 will be specifically described with reference to a specific example.

<2. Combination/separation of multiple lists>

The GPU 112 displays a plurality of lists as described above, and combines sub-lists 25 into the target list 23 or separates list items 21 from the target list 23 in response to user operations, thereby increasing/decreasing the number of displayed list items 21 (list number of items). Hereinafter, coupling of a plurality of lists and separation of lists will be sequentially described with reference to the drawings.

[2-1. Combination of multiple lists]

FIG. 3 is a diagram showing an exemplary display of a plurality of lists. As shown in FIG. 3 , the GPU 112 performs control such that a screen 31 displaying a target list 23 and a plurality of sub-lists 25 each including list items 21 is displayed on the display 15.

As shown in FIG. 3 , the list items 21 of the target list 23 are displayed in a larger size than the list items 21 of the sub-list 25 a displayed above the target list 23 . In addition, the list items 21 of the sub-list 25a are displayed in a larger size than the list items 21 of the sub-list 25b displayed above the sub-list 25a.

When a plurality of lists are displayed as described above, if a user operation indicating the combination of the lists is detected, the GPU 112 performs display control so that the list items 21 of the sub list 25 gradually move closer to the target list 23, thereby being combined into Target list 23. For example, the joining of lists is performed using an animation such as that shown in FIG. 4 .

FIG. 4 is a screen transition diagram illustrating an animation of coupling of a plurality of lists. As shown in frame 33 in FIG. 4 , GPU 112 displays target list 23 and sublist 25. When detecting a user operation indicating combination of lists, the GPU 112 performs display control so that the lists are combined as shown in a screen 35.

Specifically, as shown in screen 35, GPU 112 widens the space between each list item of target list 23, and moves each list item of sub-list 25a toward the space between each list item of target list 23. space. As described above, when the list items to be combined into the target list 23 gradually move toward the target list 23, the user can check the list items to be added through the combination before the combination is completed. Also, in this case, the GPU 112 gradually lowers the position of the sub-list 25b by one level, and adjusts the size of the list items of the sub-list 25b as shown in the screen 35.

Then, as shown in the screen 37, the GPU 112 adjusts the size and position of the list items of the sublist 25a so that they become uniform, and ends the join. Compared with the target list 23 before combining, the target list 23x obtained after combining has an increased amount of information.

Also, in the example shown in FIG. 4, when the GPU 112 has combined the sublist 25a, each of the remaining sublists is displayed at a position one layer lower. Thus, a new sublist 25c appears as shown in screen 37 .

As described above, when the GPU 112 according to this embodiment displays a plurality of lists on the screen and moves each list item 21 of the list to be added in response to a user operation, it becomes possible for the user to check in advance the list items to be added by the combination before the combination is completed. Added list item 21. In addition, although the GPU 112 displays the sublists 25 refined at each layer, when the refinement limit is reached, the number of displayed sublists 25 becomes zero. Therefore, the user can intuitively understand that refinement of the target list 23 is no longer possible.

The combination of multiple lists has been described above. Although the above example shows the case in which the sub list 25a is combined to the target list 23, the combination of a plurality of lists according to the present disclosure is not limited thereto. For example, sub-lists at multiple levels such as sub-list 25 a and sub-list 25 b may be combined into target list 23 .

[2-2. List separation]

Next, separation of lists will be described. The GPU 112 first separates a predetermined number of list items from the target list 23 in response to a user operation, thereby reducing the amount of information of the target list 23. Then, the GPU112 creates a new sub-list 25 by arranging the list items 21 separated from the target list 23, thereby completing the separation of the list.

The GPU 112 may perform animation of such a split list in the reverse order to the animation of the combined list shown in frames 33 to 37 in FIG. 4 . Specifically, the GPU 112 performs display control so that the list item 21 to be separated from the target list 23 gradually becomes smaller in size and moves away from the target list 23. The GPU 112 then creates a new sub-list 25 by arranging the separated list items 21.

As described above, when the GPU 112 according to this embodiment gradually changes the display of the list items 21 to be separated from the target list 23, the user can check in advance the list items 21 to be reduced by separation.

The separation of lists has been described above. Note that each sublist 25 to be newly created after being separated from the target list 23 may be arranged at one or more layers.

[2-3. User operation]

The above-described joining/separating of lists is performed in conjunction with various user operations. Examples of user operations include a pinch-in operation, a pinch-in operation, a drag operation, a flick operation, a tap/double-tap operation, and a button/bar operation. Hereinafter, coupling/separation of lists performed by the GPU 112 in response to each detected user operation will be sequentially described with reference to the drawings.

(open operation)

When a stretch operation is detected, GPU 112 joins the lists according to the stretch operation. Note that the pinch operation refers to a touch operation of widening the gap between two fingers when two points on the screen are touched with two fingers. Hereinafter, a specific description will be made with reference to FIGS. 5 and 6 .

FIG. 5 is a diagram illustrating a user's pinch-out operation. As shown in frame 39 in FIG. 5 , when a stretch operation on target list 23 is detected, GPU 112 joins the lists.

FIG. 6 is a screen transition diagram illustrating an animation when lists are combined in combination with a pinch-out operation. As shown in the screen 41 in FIG. 6 , in the case of touching the list item A2 and the list item A3 , an operation of widening the gap d1 between the touched positions (pinch out operation) is performed. The GPU 112 moves the display positions of the list item A2 and the list item A3 according to the user's touch position.

Next, as shown in the screen 43, when the gap d2 between the touch positions exceeds the threshold, the list item B2 of the sub-list 25a is automatically moved and inserted in the space between the list item A2 and the list item A3 . At this time, other list items of the sub list 25 a such as list item B1 and list item B3 are similarly inserted in the space between each list item of the target list 23 . Note that when an operation of narrowing the gap between the touch positions of the two fingers performing the spread operation is detected, the GPU 112 performs display control so that the union of the lists is canceled, and the list items B2 and the like are restored to their originals Show location.

Then, as shown in screen 45 in FIG. 6 , GPU 112 enlarges list item B2 inserted in the space between list item A2 and list item A3 to be similar in size to each list item of target list 23. size, thus completing the combination of lists.

As described above, the GPU 112 combines the sublists 25 displayed on the screen to the object list 23 according to the pinch-out operation, thereby increasing the information amount of the object list 23. When the sub-list 25 to be combined is displayed on the screen, the user can check in advance the list items 21 of the sub-list 25 to be combined into the target list 23 .

In addition, the user is also able to cancel the combining of lists before the combining of lists is completed while viewing information added by combining.

Although the example shown in FIG. 6 illustrates a view in which a single sub-list 25 is combined, the combination of lists by the splay operation according to this embodiment is not limited thereto, and the GPU 112 can be used in accordance with the magnitude of the splay operation. Multi-layer execution combined. For example, when the gap d2 between touch positions exceeds twice the width of the list item B2, the GPU 112 performs combining at two layers. That is, the GPU 112 performs display control so that the sublist 25a and the sublist 25b are joined to the target list 23.

In addition, although the above-described embodiment describes detecting a pinch operation of touching two list items of the target list 23 with two fingers and widening the gap between the fingers, the position of the pinch operation according to this embodiment is not limited thereto. Wherever the pinch operation is detected on the screen, the GPU 112 combines the lists according to the width of the gap d between the touch locations and the movement to widen the gap d if the screen is touched.

An example of application of the detection position of the opening operation will be described with reference to FIG. 7 . FIG. 7 is a diagram illustrating another pinch-out operation by the user. As shown in a screen 47 in FIG. 7 , the user performs a pinch operation of widening the gap between two fingers at a given position, for example, on a single list item. The GPU 112 then combines the lists according to the distance of the widened gap d5 between the two fingers.

(knead operation)

When a pinch operation is detected, GPU 112 separates the list according to the pinch operation. Note that a pinch operation refers to a touch operation of narrowing the gap between two fingers when two points on the screen are touched with two fingers. Hereinafter, description will be made specifically with reference to FIGS. 8 and 9 .

FIG. 8 is a diagram illustrating a user's pinch-in operation. As shown in a screen 49 in FIG. 8, when a pinch-in operation on the target list 23 is detected, the GPU 112 separates the list.

FIG. 9 is a screen transition diagram illustrating an animation when a list is separated in combination with a pinch-in operation. As shown in the screen 51 in FIG. 9 , in the case of touching the list item A2 and the list item A4 , an operation (pinch-in operation) of narrowing the gap d3 between the touched positions is performed. The GPU 112 moves the display positions of the list item A2 and the list item A4 so that they move closer to each other according to the user's touch position. In addition, the GPU 112 displays the list item A3 such that the list item A3 is gradually shrunk according to the pinch-in operation.

Next, as shown in the screen 53, when the gap d4 between the touch positions exceeds the threshold, the GPU 112 performs display control so that the list item A3 is moved away from the target list 23 and separated therefrom. At this time, other list items of the target list 23, for example, every other list item arranged in the target list 23, such as the list item A1 and the list item A5, are automatically moved to be separated. Note that when an operation of widening the gap between the touch positions of the two fingers performing the pinch operation is detected, the GPU 112 performs display control so that the separation of the list is canceled, and the list items A3 and the like are restored to their initial display Location.

Then, as shown in a screen 55 in FIG. 9 , the GPU 112 creates a new sub-list 25x by arranging the list items A1, A3, and A5 separated from the target list 23. In addition, as shown in the screen 55, the GPU 112 adjusts the display position of each list item of the target list 23x whose number of list items has been reduced by the separation of the list.

As described above, the GPU 112 separates a predetermined number of list items from the target list 23 displayed on the screen according to a pinch operation, and creates a new sub-list 25x by arranging the predetermined number of separated list items.

When the list items to be separated from the target list 23 are gradually shrunk, the user can check in advance which list items are to be separated before the separation is completed.

In addition, the user can also cancel the separation of the list before the separation of the list is completed while viewing the information of the target list 23 reduced by the separation.

Although the example shown in FIG. 9 illustrates a view in which one or more new sub-lists 25x are created, the separation of lists by pinching operations according to this embodiment is not limited thereto, and the GPU 112 may operation to newly create a plurality of sublists 25 . For example, if a pinch operation is performed when the gap d3 between touch positions is twice the width of the list items, the GPU 112 newly creates two sub-lists 25.

In addition, although the above embodiment describes a pinch operation of narrowing the gap between fingers while touching two list items of the target list 23 using two fingers, the position of the pinch operation according to this embodiment is not limited thereto. Wherever a pinch operation is detected on the screen, the GPU 112 separates the list according to the width of the gap d between the touched positions and the movement to narrow the gap d if the screen is touched.

(drag operation)

Next, a case where the GPU 112 combines/separates lists according to a drag operation will be described. Note that the drag operation refers to a touch operation of moving a finger while touching one point on the screen with the finger. Hereinafter, combining of lists performed in combination with a drag operation is described with reference to FIGS. 10 and 11 .

FIG. 10 is a diagram illustrating a user's drag operation. As shown in the screen 57 in FIG. 10 , when a drag operation to move the list item B2 of the sub-list 25a to the target list 23 is detected, the GPU 112 combines the lists.

FIG. 11 is a screen transition diagram illustrating an animation when a list is combined in combination with a drag operation. As shown in the screen 61 in FIG. 11 , the GPU 112 moves the list item B2 in the downward direction according to the drag operation, and also moves the other list items B1 and B3 of the operation target sub-list 25a in the downward direction. In addition, the GPU 112 performs display control such that when the list item B2 moves closer to the target list 23, the space between each list item of the target list 23 widens.

Next, as shown in the screen 63 in FIG. 11, the user drags the list item B2 to the widened space between each list item of the target list 23, and then lifts the touching finger off the screen.

Here, the GPU 112 may accept the uncoupling of the lists until the list item B2 is dragged to a predetermined position in the target list 23. For example, when a drag operation of moving back the list item B2 in the upward direction in the touch state is detected, the GPU 112 performs display control so that the position of each list item is restored to the original position.

Then, as shown in a screen 65 in FIG. 11 , the GPU 112 enlarges the list item B2 dragged to a position in the target list 23 so that the size of the list item B2 becomes similar to each list item of the target list 23 , thus completing the combination of lists.

As described above, the GPU 112 combines the sublist 25 displayed on the screen to the target list 23 according to the drag operation, and increases the information amount of the target list 23. When the sub-list 25 to be combined is displayed on the screen, the user can check in advance the list items 21 of the sub-list 25 to be combined into the target list 23 .

In addition, the user is also able to cancel the combining of lists before the combining of lists is completed while viewing information added by combining.

Combination of lists by drag operation has been described above. Next, separation of the list by drag operation will be described.

When detecting an operation of dragging the list item of the target list 23 in the upward direction, the GPU 112 separates the list. As an animation when the list is separated, for example, when the list item A2 is dragged in the upward direction, the GPU 112 displays the list item A2 so that it gradually becomes smaller. In addition, the GPU 112 simultaneously displays other list items A to be separated from the target list 23 so that they gradually become smaller while moving them in the upward direction.

In addition, the GPU 112 arranges each of the remaining list items of the target list 23 whose number of list items has been reduced by separation of the list so that the space between each list item is narrowed.

In addition, the GPU 112 creates a new sublist by arranging the list items separated from the target list 23 so that they are arranged on top of the target list 23, thereby completing the separation of the lists.

The coupling/separation of lists by drag operation has been described above. Such coupling/separation of lists is performed by moving a single list item via a drag operation. However, individual list items can also be moved by flicking instead of dragging. Hereinafter, coupling/separation of lists performed in conjunction with a flick operation will be described.

(flick operation)

The flick operation refers to a touch operation of lightly sweeping the finger in one direction while touching one point on the screen with the finger. The GPU 112 joins/separates lists by flick operation.

The animation when lists are combined by a flick operation is substantially similar to the animation when lists are combined by a drag operation described with reference to FIG. 11 . For example, when an operation of touching the list item B2 of the sub-list 25 with a finger and swiping the finger in the downward direction is detected, the GPU 112 moves each list item of the sub-list 25a in the downward direction. In addition, the GPU 112 performs display control such that the space between each list item of the target list 23 is widened.

Then, each list item of the sub-list 25 a moves to the widened space between each list item of the target list 23 . The GPU 112 enlarges each of the moved list items of the sub-list 25a to a size similar to the size of each list item of the target list 23, thereby completing the joining of the lists.

Note that when the GPU 112 moves the list item B2 according to the user's flick speed, there may be cases where the list item B2 may not reach a point in the target list 23 depending on the flick speed. In such a case, the GPU 112 may perform display control so that the display position of each list item is restored to the original position.

Coupling of lists by flick operations has been described above. Next, the separation of the list by the flick operation will be described.

When detecting an operation of flicking a list item of the target list 23 in the upward direction, the GPU 112 separates the list. As an animation when the list is separated, for example, when the list item A2 is flicked in the upward direction, the GPU 112 moves the list item A2 in the upward direction while gradually displaying the list item A2 in a smaller size. At the same time, the GPU 112 also displays other list items A separated from the target list 23 in a smaller size while moving them in the upward direction.

The GPU 112 arranges each of the remaining list items of the target list 23 whose number of list items has been reduced by separation of the list so that the space between each list item is narrowed.

Then, the GPU 112 creates a new sublist by arranging the list items separated from the target list 23 on top of the target list 23, thereby completing the separation of the list.

(tap/tap operation)

Additionally, the GPU 112 can combine/split lists in combination with tap/double tap operations. For example, each of the tapped/double-clicked list items of the sub list 25a moves to the space between each list item of the target list 23 shown in FIG. 4 , thereby completing the joining of the lists.

Meanwhile, when a tap/tap operation is performed on the target list 23, the GPU 112 separates a predetermined number of list items from the target list 23, thereby reducing the amount of information of the target list 23. Then, the GPU 112 creates a new sublist by arranging the list items separated from the target list 23, thereby completing the separation of the list.

(button/bar operation)

GPU 112 can also join/split lists in response to user manipulation of buttons or bars. Hereinafter, description will be made specifically with reference to FIGS. 12 and 13 .

FIG. 12 is a diagram showing the zoom-in button 27 and the zoom-out button 28 . When detecting a user operation on the zoom-in button 27 shown in FIG. 12, the GPU 112 separates a predetermined number of list items from the target list 23, and creates a new sub-list 25 by arranging the separated list items, thereby completing List separation.

Simultaneously, when detecting the user operation on zoom-out button 28 shown in FIG. The size of the list item to move, thus completing the list join.

FIG. 13 is a diagram showing the slide bar 29 . When detecting a user's operation of moving the knob of the slide bar 29 shown in FIG. 13 in the “−” direction, the GPU 112 separates a predetermined number of list items from the target list 23. The GPU 112 then completes the separation of the list by arranging the separated list items to create a new sub-list 25.

Simultaneously, when detecting the user's operation of moving the knob of the slide bar 29 shown in FIG. space between and adjust the size of each moved list item, thus completing the join of the lists.

Note that when the knob of the slide bar 29 is moved closer to the "minus" sign, the GPU 112 reduces the amount of information of the target list 23 changed by the combination/separation of list items, and when the knob of the slide bar 29 is moved closer to the "plus" sign ” symbol, the GPU 112 increases the amount of information in the target list 23 (increases the refinement level).

The coupling/separation of a plurality of lists performed in conjunction with user operations has been described in detail. Next, another method for displaying such a plurality of lists will be described.

[2-4. Other Exemplary Display of Multiple Lists]

In the example shown in FIG. 1 , the GPU 112 displays a plurality of lists vertically in a step-by-step manner, each list having list items 21 arranged horizontally. However, the method of displaying a plurality of lists according to this embodiment is not limited to the example shown in FIG. 1 . Hereinafter, another example of displaying a plurality of lists will be described with reference to FIGS. 14 and 15 .

FIG. 14 is a diagram showing an exemplary display in which a plurality of lists are arranged vertically. As shown in FIG. 14 , the GPU 112 arranges a plurality of lists in the horizontal direction in a stepwise manner, where each list has list items 21 arranged in the vertical direction. In this case, when a pinch-out/pinch operation on the target list 23 is detected, for example, the GPU 112 joins/separates the lists.

Fig. 15 is a diagram illustrating an exemplary display in which a plurality of lists overlap. As shown in screen 69 in FIG. 15 , GPU 112 displays target list 23 so that it overlaps sublist 25. The user is able to view each list item of the sub-list 25 between each list item of the target list 23 .

When detecting the pinching operation on the target list 23 displayed in this way, the GPU 112 moves each list item of the target list 23 in the horizontal direction according to the pinching operation shown in the screen 71 in FIG. 15 . At the same time, the GPU 112 also performs control such that each list item of the sub-list 25 is gradually enlarged, thereby displaying the target list 23x in which the sub-list 25 is joined to the target list 23x.

[2-5. Changes in displayed information]

Next, how to change the information of the displayed list by combining/separating the lists will be described. As described above, when lists are combined, the number of list items of the target list 23 increases, and when lists are separated, the number of list items of the target list 23 decreases. Such a change in information of the displayed target list 23 according to a change in the number of list items (information volume) will be described in detail below with reference to a specific example.

(first example: granularity of information)

As a first example, when the number of list items of the target list 23 increases, the granularity of information becomes finer, and when the number of list items of the target list 23 decreases, the granularity of information becomes coarse. The granularity of information will be specifically described with reference to FIGS. 16 to 18 . 16 to 18 exemplarily illustrate thumbnail images as list items created from scenes of moving image data every predetermined time period.

FIG. 16 is a diagram of a screen 72 displaying a plurality of lists each including a plurality of thumbnail images. As shown in FIG. 16 , the target list 73 is a list of scenes in which moving image data every one minute is arranged.

In addition, as shown in FIG. 16 , the sub list 75 a is a list in which scenes are arranged, each scene to be inserted between scenes of the target list 73 every minute. For example, the sub-list 75a includes arranged therein: a thumbnail image at 4:30, which is to be inserted between the thumbnail image at 4:00 and the thumbnail image at 5:00 of the target list 73; a thumbnail image at 5:30, which To be inserted between the 5:00 thumbnail and the 6:00 thumbnail of the target list 73; and the 6:30 thumbnail, which is to be inserted between the 6:00 thumbnail and the 7:00 thumbnail of the target list 73 00 between the thumbnails; and so on.

In addition, as shown in FIG. 16 , the sub-list 75 b is a list in which scenes are arranged, two of which are to be inserted between the scenes arranged in the sub-list 75 a. For example, the thumbnail images of 4:45 and 5:15 to be inserted between the thumbnail image of 4:30 and the thumbnail image of 5:30 of the sub list 75 a are arranged.

Then, when detecting a user operation indicating to combine a plurality of lists shown in FIG. 16 , GPU 112 combines sublist 75 a to target list 73 , whereby the number of list items of target list 73 increases. A case in which the number of list items of the target list 73 shown in FIG. 16 is increased will be described with reference to FIG. 17 .

FIG. 17 is a graph showing results obtained when combining the lists shown in FIG. 16 . The target list 73x shown in FIG. 17 is obtained by combining the sub-list 75a shown in FIG. 16 to the target list 73. By combining the lists, the number of list items of the target list 73x is increased so that thumbnails every 30 seconds are arranged. As described above, when the number of list items is increased by combining lists, the granularity of information becomes finer.

FIG. 18 is a graph showing results obtained when separating the plurality of lists shown in FIG. 16 . The target list 73y shown in FIG. 18 is obtained by separating the lists from the target list 73 shown in FIG. 16 . In addition, the sublist 75x shown in FIG. 18 is a sublist newly created by arranging list items separated from the target list 73 shown in FIG. 16 . By the separation of lists, the number of list items of the target list 73y is reduced so that list items every two minutes are arranged. As described above, when the number of list items is reduced by separation of lists, the granularity of information becomes coarse.

(Second example: type of information)

As a second example, when the number of list items of the target list 73 increases, the types of information increase, and when the number of list items of the target list 73 decreases, the types of information decrease. The types of information will be specifically described with reference to FIGS. 19 to 21 . 19 to 21 exemplarily illustrate types of information related to music data as list items.

FIG. 19 is a diagram showing a screen 81 displaying a plurality of lists created based on information related to music data. As shown in FIG. 19, the target list 83 is a list in which cover images of music albums are arranged.

The sublist 85a is a list in which the names of the individual pieces of music on each music album are arranged. In addition, the sub-list 85b is a list in which the lyrics of each piece of music are arranged.

When a user operation indicating combination of a plurality of lists shown in FIG. 19 is detected, the GPU 112 combines the sublist 85a to the target list 83, whereby the number of list items of the target list 83 increases. A case where the number of list items of the target list 83 shown in FIG. 19 is increased will be described with reference to FIG. 20 .

FIG. 20 is a graph showing results obtained when combining the lists shown in FIG. 19 . The target list 83x shown in FIG. 20 is obtained by combining the sub-list 85a shown in FIG. 19 to the target list 83. By combining lists, the number of list items of the object list 83x is increased, and images of music covers and lists of individual pieces of music are arranged. As described above, when the number of list items is increased by combining lists, the types of information increase.

Note that, as shown in FIG. 20, the GPU 112 can change the background for each relevant information (list item) in the target list 83x.

FIG. 21 is a diagram showing the results obtained when the two sublists 85 shown in FIG. 19 are joined to the target list. The target list 83 y shown in FIG. 21 is obtained by combining the sub-list 85 a and the sub-list 85 b shown in FIG. 19 to the target list 83 . By combining the lists, the number of list items of the target list 83y is increased, and images of music covers, lists of individual pieces of music, and lyrics of each piece of music are arranged. As described above, when the number of list items is increased by combining lists, the types of information increase.

Note that in the example shown in FIG. 21 , the background can also be changed for each related information (list item) in the target list 83y. In addition, as shown in FIG. 21 , the GPU 112 may also combine each of the sublist 85a and the sublist 85b to the target list 83 without changing the display size of each list item of the sublist 85a and the sublist 85b.

The type of information is not limited to the type of information related to the music data given as examples in FIGS. 19 and 21 . For example, the types of information may be classified in a step-by-step manner according to the degree of enthusiasm of each scene of moving image data. Specifically, the control unit 11 analyzes the moving image data in advance, and the GPU 112 creates a first list by arranging thumbnail images of scenes with the highest degree of enthusiasm. The GPU 112 then adds the scene with the next highest degree of enthusiasm to the first list by combining.

The above-described change in display information associated with coupling/separation of a plurality of lists is also true for <3. Coupling/Separation of List Items of a Single List>.

<3. Combination/separation of list items of a single list>

As described above, the GPU 112 according to this embodiment can also display a single list in response to a user operation, and combine/separate list items of the list. GPU 112 increases the number of list items of a single list displayed in response to a user operation indicating a join of lists.

In addition, the GPU 112 reduces the number of list items of the displayed single list in response to a user operation indicating separation of the list, and creates a new sub-list by arranging the list items separated from the single list.

Here, examples of user operations indicating coupling/separation of list items of a single list include pinch-in/pinch operations, tap/double-tap operations, and button/bar operations described in [2-3. User Operation]. For specific control of coupling/separation of list items of a single list described below, a case where a pinch-in/out operation is detected as a user operation will be exemplarily described.

[3-1. Combination of list items of a single list]

GPU 112 causes new list items to gradually appear in the list in response to a user operation indicating the joining of the lists, thereby increasing the number of list items. Hereinafter, coupling of list items of a single list will be described with reference to FIGS. 22 and 23 .

FIG. 22 is a diagram showing a screen 91 displaying a target list 93 . As shown in FIG. 22 , a pinch-out operation is detected: list items A2 and A3 of the target list 93 are touched with two fingers, and the gap between the two touched positions is widened with the screen touched. The GPU 112 then combines the list items of the target list 93 according to the stretching operation.

FIG. 23 is a screen transition diagram illustrating an animation when list items are combined in combination with a pinch-out operation. As shown in the screen 95 in FIG. 23 , an operation of increasing the gap between the two touched positions (pinch out operation) in the case of touching the list item A2 and the list item A3 is performed. The GPU 112 moves the display positions of the list item A2 and the list item A3 according to the user's touch position.

Next, as shown in screens 97 and 99 , new list items gradually appear in the space between each list item of the target list 93 widened by the pinching operation.

Then, the GPU 112 enlarges the list items that appear between each list item of the target list 93, so that the size of the list items becomes similar to the size of each list item of the target list 93, thereby completing the combination of the list items .

Note that the GPU 112 may uncoupling list items and hide new list items when detecting an operation that narrows the gap between the touch positions of the two fingers performing the pinch operation.

As described above, when the GPU 112 causes new list items to gradually appear in the target list 93 according to the pinching operation, the user can preview list items to be combined into the target list 93.

In addition, the user is also able to cancel the combination of the list items before completing the combination of the list items while viewing the information added by the combination.

[3-2. Separation of list items]

The GPU 112 may cause a predetermined number of list items of a single displayed target list to gradually disappear according to a pinch operation, thereby separating the list items. When the list items in the target list gradually disappear, the user can preview the list items to be separated from the target list in advance.

In addition, the GPU 112 may, when detecting an operation of widening the gap between the touch positions of the two fingers performing the pinch operation, cancel the separation of the list items, and make the list items that have disappeared once appear again.

[3-3. List display]

The above examples have described increasing/decreasing the number of list items by combining/separating list items of a single list. Here, when the number of list items is increased by combining list items, some list items are excluded from the screen.

Here, the GPU 112 according to this embodiment can enlarge/shrink the display size of the list items when the number of list items of the target list is increased or decreased by combining the list items, thereby performing displaying all the list items within the screen. The list is displayed. When the GPU 112 performs list display, the user can view all list items added by combining list items within the screen. The list display of the GPU 112 will be described with reference to FIGS. 24 to 26 . In FIGS. 24 to 26 , thumbnail images created from scenes of moving image data every predetermined period of time are displayed as list items in the form of a grid list.

FIG. 24 is a diagram of a screen 201 for list displaying a single list. As shown in a screen 201 in FIG. 24 , the GPU 112 arranges all the thumbnails of the moving image data every two minutes. An animation when list items are combined in response to a user operation will be described with reference to FIGS. 25 and 26 .

FIG. 25 is a diagram showing a screen 203 displaying animation when list items are being combined. As shown in FIG. 25, GPU 112 shrinks each thumbnail and causes new thumbnails to gradually appear between each thumbnail.

FIG. 26 is a diagram showing a screen 205 when coupling of list items is completed. As shown in a screen 205 in FIG. 26, even when the number of list items is increased by combining list items, the GPU 112 displays all thumbnails on a single screen.

The case where a single list is displayed as an example of the above list display has been described above. However, the GPU 112 can also control the display of lists when combining multiple lists.

<4. Operation processing>

Next, operation processing performed when the GPU 112 according to this embodiment performs the above-mentioned display control of the joint/separation list according to the movement amount or the movement speed of the pinch-in/pinch operation will be described. Although FIGS. 6 and 9 illustrate examples in which the GPU 112 performs display control of combining/separating lists according to the gap d between two fingers performing pinching/pinching operations, respectively, the embodiment is not limited thereto. For example, the GPU 112 can also combine/separate lists according to, for example, the amount of movement of a finger performing a touch operation or the speed of movement of a finger. Hereinafter, operation processing performed when the GPU 112 combines/separates lists according to the movement amount or movement speed of the pinch/pinch operation will be described with reference to FIG. 27 .

FIG. 27 is a flowchart showing a display control process of combining/separating lists according to a movement amount or a movement speed of a pinch-in/pinch operation. As shown in FIG. 27 , when the touch panel 16 detects two touches in step S102 , the touch panel 16 further detects a pinch/pinch operation based on the movement of the operation positions of the two touches in the next step S104 . The touch panel 16 outputs a detection result to the control unit 11 when detecting a pinch-in/out operation.

Next, in step S106, the GPU 112 of the control unit starts animation of the join/separate list displayed on the display 15 according to the pinch-out/pinch operation detected by the touch panel 16. For example, the GPU 112 moves a touched list item according to a pinch/pinch operation.

Next, in step S108, when the touch panel 16 detects an operation of touching two points, the process proceeds to step S110. Next, in step S110, the GPU 112 determines whether the movement amount of the pinch/pinch operation is greater than a threshold. For example, the movement amount of the pinch/pinch operation used here is calculated as shown in FIG. 28 .

FIG. 28 is a table exemplarily showing calculation of a movement amount and a movement speed of a pinch/pinch operation. As shown in FIG. 28 , the movement amount of each pinch/pinch operation is the sum of the distances of movement of the list items from the initial state in the pinch/pinch operation.

Alternatively, the movement amount of each pinch/pinch operation may be the sum of the distances moved by each of the two touch positions of the pinch/pinch operation.

In step S110 described above, if the movement amount of the pinch/pinch operation exceeds the threshold value, the process proceeds to step S112. Next, in step S112, the GPU 112 joins/separates the lists. Note that if the movement amount exceeds the first threshold in step S110, joining/separation of lists at one level is performed in step S112. For example, combining individual sublists, or creating a single sublist by detaching.

Next, the process proceeds to step S108, and the pinch/pinch operation is further continued. Then, if the movement amount exceeds the second threshold in step S110, the GPU 112 performs joining/separating of lists at another layer. For example, the GPU 112 then combines a sublist, or creates another sublist by splitting. As described above, the GPU 112 performs coupling/separation of lists in multiple layers according to the pinch/pop operation.

Next, referring to step S108 again, a case where two touches are no longer detected will be described. In this case, the process proceeds to step S114, and the GPU 112 determines in step S114 whether the speed of the pinch-in/out operation exceeds a threshold. The speed of the pinch/pinch operation used here is, for example, the sum of the moving speeds of each list item in the pinch/pinch operation shown in FIG. 28 .

If the movement speed of the pinch/pinch operation exceeds the threshold value in the above-described step S114, the process proceeds to step S116. Next, in step S116, the GPU 112 executes joining/separating of lists. Note that if the movement speed exceeds the first threshold in step S114, joining/separation of lists at one level is performed in step S116. For example, combining individual sublists, or creating a single sublist by detaching.

Next, the process returns to step S114, and if the movement speed is still not zero, the GPU 112 again performs coupling/separation of lists at another layer in step S116. For example, the GPU 112 then combines a sublist, or creates another sublist by splitting. As described above, the GPU 112 performs coupling/separation of lists at multiple layers according to the speed of list items moved in accordance with the pinch-out/pinch operation.

Meanwhile, if the speed does not exceed the threshold in step S114, the process proceeds to step S118. In step S118, the GPU 112 determines whether the movement amount of the pinch/pinch operation exceeds a threshold. If the movement amount exceeds the threshold, the process proceeds to step S120.

Next, in step S120, the GPU 112 performs join/separate of lists. Note that the GPU 112 may also have a plurality of thresholds, and may control the combined/separated layers of the list according to which threshold the movement amount of the pinch-in/pinch operation has exceeded. For example, if the movement amount of the pinch/pinch operation exceeds the threshold a, the GPU 112 combines sublists or creates sublists by splitting. Meanwhile, if the movement amount of the pinch-in/out operation exceeds the threshold b, the GPU 112 combines the two sub-lists or creates two sub-lists by separating.

Next, in step S122, the GPU 112 finishes the animation of combining/separating lists.

<5. Conclusion>

As described above, according to the information processing apparatus 10 according to this embodiment, the user can check in advance the list items to be combined into the sub list 25 of the target list 23 before the combining is completed by displaying a plurality of lists on the screen.

In addition, according to the information processing apparatus 10 according to this embodiment, even when a single list is displayed on the screen, if new list items gradually appear in the list in response to a user operation, the user can check in advance before the integration is completed. The list item to add.

In addition, when the list items to be separated from the target list 23 are gradually changed according to the user's operation, the user can check in advance the list items to be removed from the target list 23 by the separation of the list items.

In addition, the user is also able to cancel the combining or separating of the list before it is completed while viewing the list items that are increased or decreased by the animation of combining or separating the lists.

In addition, when the number of list items is increased by combining list items, the GPU 112 can display more detailed information while securing the list properties of the list by controlling all list items so that they are displayed within the screen.

It will be apparent to those skilled in the art that various modifications or changes may be made so long as they are within the technical scope of the appended claims or their equivalents. It should be understood that such modifications or variations are also within the technical scope of the present disclosure.

For example, although the animation when lists are combined in conjunction with the pinch-out operation in the above [2-3. User operation] has been described with reference to FIG. 6 , the animation when lists are combined is not limited to the example shown in FIG. 6 . For example, each list item of the sub-list 25a to be combined may be gradually enlarged substantially simultaneously with the start of movement of the list item to the target list 23, and may be substantially at the same time as each list item in the target list 23. Inserts the end of the list item between items and ends zooming in on the list item. FIG. 29 shows an example of changing the animation when the list is combined in combination with the pinch operation as described above. As shown in the screen 44 in FIG. 29 , when the gap d2 between the touch positions exceeds the threshold value, the list item B2 of the sub list 25 b moves while being gradually enlarged. Then, as shown in the screen 46 , the enlargement of the list item basically ends at the same time as when the list item is inserted between the list item A2 and the list item A3 .

Although the target list 23, the sub-list 25a, and the sub-list 25b are sequentially displayed in the above-described embodiment, each list may be switched or all lists may be moved according to user operations.
